Al-Khateeb Al-Baghdadi reported: Al-Bukhari, may Allah have mercy on him, said, “The best of the Muslims is a man who revives one of the traditions of the Prophet, peace and blessings be upon him, after it has died out. O followers of the Sunnah, be patient and Allah will have mercy on you, for you are a minority among people.”
